Correct Answer: A

Rationale: The ABG results indicate respiratory acidosis due to an elevated PaCO2 (49 mm/Hg), indicating hypoventilation. The appropriate intervention for respiratory acidosis is to improve ventilation. Coughing and deep breathing protocols can help the client to effectively ventilate and improve gas exchange. Administering oxygen via nasal cannula (Choice B) may be necessary in respiratory distress situations, but addressing the underlying cause of hypoventilation is crucial. Intubation and mechanical ventilation (Choice C) are not the first-line interventions for uncomplicated respiratory acidosis. Increasing IV fluids (Choice D) does not directly address the respiratory acidosis present in this scenario.

Correct Answer: A

Rationale: Talking directly to the adolescent is the most appropriate intervention in this scenario. It helps maintain a sense of connection and respect, even if the response is not evident. Maintaining silence may lead to isolation and hinder any potential communication attempts. Playing soothing music may not provide the personal interaction needed for connection. Limiting visitors to immediate family only may deprive the patient of diverse interactions that could be beneficial for their emotional well-being.

Correct Answer: B

Rationale: Reorienting the client frequently is the most important nursing intervention in this scenario. It helps reduce confusion and agitation, which are common symptoms of acute delirium in hospitalized elderly clients. Requesting a psychiatric consult (choice A) may be necessary if the reorientation does not improve the client's condition or if there are underlying psychiatric concerns, but reorientation should be attempted first. Administering antipsychotic medications (choice C) should not be the initial intervention as they can have adverse effects in elderly individuals. Obtaining a sitter (choice D) may provide support but does not directly address the client's disorientation and agitation.

Correct Answer: B

Rationale: The most important intervention for the nurse to implement is to schedule weekly home visits to draw hCG values. Monitoring hCG levels is crucial in detecting potential complications like choriocarcinoma following GTD evacuation. Teaching about home pregnancy tests (Choice A) may not be as immediate and critical as monitoring hCG levels. A 5-week follow-up appointment (Choice C) may be too delayed for close monitoring. Initiating chemotherapy (Choice D) without appropriate hCG monitoring and evaluation is not recommended as the first-line intervention.

Correct Answer: A

Rationale: Adhering consistently to standards of care is crucial for nurses to reduce the risk of being named in a malpractice lawsuit. Following established protocols and guidelines ensures that the care provided is safe and effective. Thoroughly documenting all client interactions is also essential to support the care provided and to have a record of the interventions. Building a good rapport with clients is important for communication and trust but does not directly reduce the risk of malpractice. Working closely with the healthcare team is valuable for collaboration but might not directly impact the risk of malpractice unless it relates to following standards of care.
